I also think that another point for consideration is that we are grown-ups, and that the "let's-censor-for-fear-that-this stuff-will-deprave-and-corrupt" mindset owned by self-appointed moralisers is both authoritarian and patronising. Most of us are a bit tougher than that, thanks, and we have brains. Not saying that in certain spheres (especially with regard to the young) that we should never draw lines. It's a difficult area all right.
